Will you be able to recruit more of the largest, fastest-firing motor units while sprinting from continued focus on deadlifting or focusing on something that requires more power?
That was my train of thought, but thanks for still checking up on this thread.
There are 3 aspects here.
1. Increasing strength in order to have more motor units to recruit.
2. Increasing storage and release of elastic energy
3. Increasing rate of force delivery.
1=Heavy lifting (deadlift or squat or?) for recruitment
2=Plyometrics for storage and release of elastic energy
3=? for increasing rate of force delivery
The simple answer to #3 has been power lifts, but as stated earlier, power lifts have significantly slower rates of force delivery than just running fast.
So why not just run fast to get faster?
The speed limit for every runner, regardless of training level, is the amount of support force (in excess of mass) delivered to the running surface during decreasing ground contact times.
